What steps will reproduce the bug?
- Download https://gist.github.com/sapphi-red/a0179b52ebd3b6a19f51743594810ecf
- Run
node eval_cjs.mjs. It exits with non-0 exit code.
a. On windows, it does not show any error messages. The output ofecho $LASTEXITCODEis-1073741819.
b. On WSL (Ubuntu), it showsSegmentation fault (core dumped). The output ofecho $?is139. - Run
node eval_cjs_cjs.cjs. It exits with non-0 exit code same witheval_cjs.mjs. - Run
noneval_cjs.mjs. It finishes without any errors. - Run
noneval_mjs.mjs. It finishes without any errors.
The difference between the files are:
| filename | parent script | worker script | is eval | result |
|---|---|---|---|---|
eval_cjs.mjs |
ESM | CJS | O | fail |
eval_cjs_cjs.cjs |
CJS | CJS | O | fail |
noneval_cjs.mjs |
ESM | CJS | X | success |
noneval_mjs.mjs |
ESM | ESM | X | success |
How often does it reproduce? Is there a required condition?
It reproduces every time on my machine. const startAt = Date.now() + 10 * 1000 might differ between machines.
I suppose at least it needs to meet the following condition:
workeris created witheval: true- dynamic import is called after
await
I am not sure why it requires 10 seconds delay.
What is the expected behavior?
Segmentation fault not happening.
What do you see instead?
Segmentation fault is happening.
